Mp4

This post is a sibling of my earlier post Using Handbrake to Encode DVDs for the Roku and contains the settings I use for Blu-Ray movies. The instructions apply to Handbrake 0.9.9.
Once again, start with the High Profile preset and then make the following changes:
In Output Settings: Set Container = Mp4 Ensure Large File Size is checked Ensure Web Optimized is checked Ensure iPod 5G Support is unchecked In Picture: Set Anamorphic = Strict (all Blu-Rays I’ve seen are 1920x1080) Set Cropping = Automatic.

In a previous post, I noted that I use ffmpeg to convert DVDs to MP4s which will play on my Roku. I recently encountered two problems with this approach. First, the resulting MP4s only include a stereo audio track, so are highly sub-optimal for surround sound systems. Second, for a yet-undetermined reason, Plex (my current preferred media client) will transcode the videos rather than play them directly.

Update 2013-12-02: I no longer use this method. See this post for my new method.
I have three (someday to be four) Roku players at home. I primarily use them to stream Netflix and Amazon Instant Video and to stream MP4s from a home server using Roksbox.
My typical workflow is to rip DVDs to VOBs using Dvdfab, copy the VOBs to my home server, and then convert them in bulk from VOB to MP4 using ffmpeg.
